Limitations of Radiography: Superimposition and Qualitative Nature

Because radiographic film is too sensitive and blurs out subtle differences.

Because typical film-screen combinations can only discriminate x-ray intensity differences of 5% to 10%. (correct)

Because radiographic film has the ability to adjust contrast after recording.

Because radiography and tomography cannot generate cross-sectional images.

CT imaging offers the ability to adjust contrast after recording.

CT imaging is less sensitive to subtle differences in tissue contrast.

CT imaging can generate cross-sectional images without superimposition of structures. (correct)

CT imaging uses film-screen combinations for image acquisition.

CT scans provide the ability to reformulate images in multiple planes. (correct)

CT scans use the same film-screen combinations as radiography.

CT scans are less detailed than radiographic images.

CT scans have lower sensitivity to subtle tissue contrast differences.
